无法使用ajax和JSON进行POST

Question

I am trying to make a POST with AJAX, but it doesn't recognize the parameters, it just does an empty POST...

Here is my ajax code :

    <script>
    $(document).ready(function() {
    $('.reserve-button').click(function(){
        $.ajax({
                type: "POST",
                dataType: "json",
                url : "generator/",
                data : {id: <?=$id?>},

                success : function(){
                    alert("Please give this code to your patient:" );
                },
                error:function(){
                    alert("Erreur!!");
                }
            });

            return false;
    });
    });

    </script>

The HTML part :

<div class= "obutton feature2" data-id="<?php echo $id;?>">
    <button class="reserve-button">Reserve Book</button>
</div>

Thank you!!

Your

{id: <?=$id?>}

isn't valid JS. First try with a hardcoded id, like

{ id: 1234 }

and if that works, then figure out why your templating code isn't correctly generating your id. : )
